The sliding plate 131 is provided with a positioning part 133, and the positioning part 133 can be matched with the material 31 at the lowest layer of the material stack 3, so as to preliminarily position the material 31 at the lowest layer of the material stack 3 and facilitate stacking of the material 31 at the upper layer. The positioning portion 133 may be a single material 31 fixedly connected to the sliding plate 131, or may be a positioning protrusion or a positioning groove provided on the sliding plate 131, wherein the shape and size of the positioning portion 133 are matched with those of the material 31, so as to ensure accurate positioning of the material stack 3, and prevent the material stack 3 from being displaced relative to the sliding plate 131 in the process of moving along with the material conveying unit 13, so as to prevent the material stack 3 from being displaced.
For a single material 31, at least one side edge is provided with a first folding edge 32 extending upwards, the material 31 is provided with an opening 35, the opening 35 is provided with a second folding edge 36 extending upwards at the side close to the diagonal rod bracket 132, the width of the opening 35 is larger than the thickness of the second folding edge 36, and the length of the opening 35 is larger than the length of the second folding edge 36; the arrangement of the first folded edge 32 is convenient for the lower material to limit the upper material, and the arrangement of the opening 35 and the second folded edge 36 enables the opening 35 of the upper material to be sleeved in the second folded edge 36 of the lower material, and the second folded edge 36 of the lower material can quickly position the upper material; in addition, the second folded edge 36 is close to one side of the diagonal rod support 132, so that the inclination direction of the material stack 3 from top to bottom is consistent with the inclination direction of the diagonal rod support 132, and the lug 34 of each piece of material can be always in abutting contact with the diagonal rod support 132.
On the basis of the structure of the feeding device, in order to further improve the automation degree in the feeding process, a first detection device 15 and a second detection device 16 are arranged at a material taking part 12 of the workbench 1, wherein the first detection device 15 is used for detecting the maximum height of a material pile, and the second detection device 16 is used for detecting the minimum height of the material pile; in addition, the workbench 1 comprises a central processing unit for managing and controlling the feeding process; meanwhile, the embodiment provides a material loading control method, which includes:
s1, the central processing unit clears the count value and controls the new material conveying unit 13 to move to the material taking part 12;
in step S1, based on the structure of the feeding device, the guide groove 101 is provided with a plurality of material conveying units 13, and when material taking is not performed for the previous material conveying unit 13 with reference to the moving direction of the material conveying unit 13 on the guide groove 101, the adjacent next material conveying unit 13 is regarded as a new material conveying unit 13; thereby removing the previous material handling unit 13 from the take-out location 12 and moving a new material handling unit 13 to the take-out location 12.
S2, the central processing unit detects the maximum height through the first detection device 15 and judges whether the actual height of the material pile is greater than the maximum height; if yes, return to step S1; otherwise, go to step S3;
preferably, the first detection device 15 is an infrared detector and detects the height of the material stack; specifically, a height limit value of the maximum height is set through an infrared detector, and whether the actual height of the material pile is greater than the maximum height is detected; therefore, under the conditions that the material pile is too much and the material pile is too high, the situation that the mechanical claw 2 cannot reach the corresponding height to cause grabbing failure can be avoided.
S3, the central processing unit detects the minimum height through the second detection device 16 and judges whether the actual height of the material pile is smaller than the minimum height; if yes, return to step S1; otherwise, go to step S4;
preferably, the second detecting device 16 is an infrared detector, and detects the height of the material stack; specifically, a height limit value of a minimum height is set through an infrared detector, and whether the actual height of the material pile is smaller than the minimum height is detected; therefore, under the conditions that the material pile is too few and the material pile is too low, the situation that grabbing fails due to the fact that the mechanical claw 2 cannot reach the corresponding height or the mechanical claw 2 is in space conflict with structures such as the sliding plate 131 can be avoided.
S4, the central processing unit controls the mechanical claw 2 to grab the material 31 in the material conveying unit 13;
after the gripper 2 grabs the material 31, the material 31 is moved and placed in a downstream process, and then the gripper 2 is reset to wait for next grabbing action.
S5, the central processing unit detects the minimum height through the second detection device 16 and judges whether the actual height of the material pile is smaller than the minimum height; if yes, return to step S1; if not, the count value is increased by 1, and the step S6 is performed;
after each grabbing action is executed, the minimum height detection is carried out, so that the feeding process and the action of the mechanical claw 2 can be adjusted effectively and timely according to the actual height condition of the material pile.
S6, the central processing unit judges whether the count value is larger than a preset value; if yes, return to step S1; otherwise, the process returns to step S4.
When the count value is larger than the preset value, the mechanical claw 2 performs a certain number of grabbing actions on one material conveying unit 13, and if the material conveying unit 13 is continuously grabbed, the actual height of the material pile may be smaller than the minimum height at any time; therefore, the arrangement of step S6 makes it possible to stop the successive grasping operations of the individual material transport units 13 in time and then start grasping a new material transport unit 13, and prevents the mechanical gripper 2 from continuing to perform a malfunction due to a failure of an individual component or an error in the above-described individual determination process. Preferably, the preset value is 20.
In addition, in this embodiment, the workbench 1 further includes a base, a housing, an electronic control component, and other structures, which are not repeated herein in view of that the related structures can be purchased or customized from the market and are all the prior art.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
